Merged
Conversation
Single-server chat application demonstrating lifecycle hooks driving real-time GraphQL subscriptions. Includes EF Core data layer (chat schema), six trains (create/join/send/read/history/rooms), a custom ITrainLifecycleHook that publishes to room-scoped HotChocolate topics, and a React + TypeScript frontend using Apollo Client with split HTTP/WebSocket transport for queries, mutations, and subscriptions.
